I Had taken out my stock radio and put in a pioneer. Took that out then put an in-dash. well yesterday i took out the in-dash since its going to the body shop tomorrow and i didnt want it stolen. well i connected everytihng back up and turns out the stupid radio says a bunch of different code sometihngs on every button i hit and now it just says CODE.E at all times. Any help, suggestions, tips, or answers to my problem for that matter? thanks for your help.

Look under the ashtray, in the glovebox, or under the fuse box lid in the engine bay to find a sticker with the code for your radio.

It differs from dealer to dealer so only if you're lucky...

Otherwise you will have to take the head unit to an Acura dealership and they will look up the code for you.

 

This is the anti-theft code. You need to find the numbers and enter them in the radio for it to work again.
